The Challenge
Established in 1981, our client manufactures 60,000 – 70,000 pounds of screws daily that are carried in Lowe’s and Home Depots nationwide.
Not surprisingly, the philosophy of this market leader is one of continuous improvement. However, sometimes changes for the better also have consequences. When the company went to a new acid- pickle bath pre-treat system on its paint line, the result downstream was far too much zinc in its wastewater effluent.
They knew they had to change their wastewater chemistry, and that’s when they called Hubbard-Hall.
The Approach
We led a team of wastewater treatment experts through a process that began by going on-site and tank side.“There’s nothing like being there to get to the bottom of things,” says Hubbard- Hall’s David Joyce, “I pulled a sixteen-hour shift. Nobody went near thatclarifier. It ran crystal clear that day.”
Initially, Hubbard-Hall recommended a custom recipe built from three products:
AquaPure 100, a custom blended inorganic coagulant
AquaPure P 601, a metal precipitant
AquaPure FW, a polymer flocculant in liquid form
Aong the way Hubbard-Hall recommended, implemented and trained the company to do jar testing to help them maintain the process. It was an idea they liked so much that it became a requirement for all shift operators.
